Please try to nail down the problem somewhat further, for instance, by providing a minimal testcase which allows to reproduce the problem with a minimum of involved code. Since this revolves around malloc, it might be worth to note that two changes to malloc have been made in Cygwin between 1.5.18 and 1.5.19. First, we switched from Doug Lea's malloc implementation version 2.8.0 to 2.8.3, second, due to a reworked mmap implementation, which uses simple VirtualAlloc for private anonymous maps, we lowered the DEFAULT_MMAP_THRESHOLD from 16 Megs to the usual default of 256K.
